GOGGLES.

Application filed January 2, 1926. Serial No. 78,914.

My invention relates to goggles, and has for its chief object, an adjustable feature of the lens, and functions as a bright light retarding means for the headlight of an approaching automobile,

A further object of my invention is to provide goggles having colored lens.

A still further object of my invention is to provide an adjusting means vthat will automatically hold the lens in a horizontal position. f

A still further object of my invention is to provide a pneumatic actuating means for the lens frame.

These and other objects will hereinafter be more fully explained with reference to the drawings wherein like figures will apply to like parts in the different views.

Referring to the drawings:

Fig. 1 is a front view of the goggles.

Fig. 2 is a top view of Fig. 1.

Fig. 3 is an end view of the goggle frame to which the detent spring is attached.

Fig. 4 is a view of the opposite end from Fig. 3, showing the dash pot and pneumatic tube.

The goggles herein disclosed consist of a frame 1 having a saddle for the nose as at 2, the ends of said frame being bent to a right angle as at A. The upper extremity of said members are provided with apertures as at B in which is trunnioned a shaft B. On the end of said shaft isv a pawl 4 integral therewith and adapted to engage with a detent 5, the said detent being integral with spring 5 which is rigidly attached to the frame as at C by means of rivets or welding.

On the right angle bends of the frame are rigidly connected brackets 6, said brackets having perforations therein in which are pivotally mounted bows 7, the said bows adapted to engage over the ears for the purpose of supporting the goggles in front of the eyes. On the oposite end of shaft 3 is a crank 8, the said crank being pivotally connected to a connecting arm 9, 10 is a dash pot adapted to receive a piston 11 to which said -connecting arm is attached. The dash pot is pivotally attached-to the frame as at 12 for the purpose of oscillation by rotation of the crank 8. Y

On the lower extremity of said dash pot is a exible pneumatic tube 13, the said tube being of proper length that the outward eX- tending end thereof may be inserted inV ing supported by annular rings 15 which are rigidly connected to shaft 3 asshown at D. When the vlenses are concentrically positionedbefore the eyes and the operator desires to remove them to a horizontal position as shown by dotted lines E, the operator will create a vacuum in the dash pot by drawing the air therefrom by means of suction through the pneumatic tube, and 'simultaneous with the movement the pawl 4 will engage with a curvature of thc detent as shown at F in Fig. 3, as supporting means for the horizont-al position, then to replace the lens to the vertical position the operator will blow through the tube, inflating the dash pot at which time the detent being resilient will release the pawl and the upper extremity of the detent as at G will engage the pawl supporting the lens in parallel alignment with the frame.

The mechanism herein disclosed is adaptable for bus, stage, or automobile drivers, and the lenses may be disengaged or placed in position before the eyes independently of the hands, although a bulb may be applied to the end of the tube and a tube of suiiicient length to be operated by the hands while holding the steering wheel; bther modifications may be employed as lie within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is zl 1. In a goggle, a frame, bows and a saddle on said frame, a shaft rotatably mounted on said frame, a pair of lenses pendantly supported by said shaft, a pawl and a detent for one end of said shaft, a' crank and a pneumatic operating means on the opposite end of said shaft so that said lenses may be horizontally positioned and detained, for the purpose described.

2. In -a goggle, a frame, a resilient detent attached to one end of the frame, a dash pot pivotally connected to the opposite end of said frame, a shaft trunnioned on said frame, supporting means forv translucent members, said means pendantly supported by said shaft,v a pawl on one end of said shaft to engage with the detent adjacent thereto, a crank on the opposite end of said shaft, a dash pot and a connecting arm in axial alignment and rockable With nseid crank, said crank and connecting arm being` pivotally connected, aJ flexible pneumatic tube attached to the lower extremity of said dash pot, means for actuating reciprocatons of said connecting arm for the purpose described, a pair of bows pivotally connected to said frame, and a nose piece functioning as a saddle to support said frame securely before the eyes of the operator, all substantially as shown and described.
